Williams was charged with felony aggravated assault for repeatedly punching Schmucker in the head in the early hours of Oct. 31, according to Lancaster Online. A warrant was issued for his arrest on Sunday, but he remains at large.

"We are actively seeking Imir," Strasburg police Chief Steven Echternach said Tuesday. "We believe he is either in (Lancaster) city or New Jersey."

Schmucker, who is simply known as Esther on the Discovery Channel series, allegedly did not file the charges until Sunday because Williams was standing guard over her to make sure she didn't turn him in to authorities. She was treated for her injuries on Halloween, but claimed another female had attacked her. After Williams left her, she alerted authorities of the truth.

This is not the first time Schmucker has filed charges against Williams for abusing her. She previously reported at least three protection-from-abuse orders against the rapper, who goes by the moniker Mirkat. The filings were all dismissed when Schmucker failed to appear for any court hearings regarding the orders.

Amish Mafia returns to Discovery with a special Christmas episode later this year. Season 3 will air in 2014.
